You might try to talk about how you are feeling–your partner turns everything around and tries to talk about everything you’re doing wrong. Even when they hurt you, they make you feel bad for the pain it has caused them. They often don’t actually feel guilty about what they have done, only that they were caught. Other people might warn you about dating your partner–if they have a track record of abuse, most likely it is only a matter of time until they abuse you. Your friends and family wish that you would break up.
If you are a peaceful person, you might find yourself constantly fighting. You feel like there is something seriously wrong with you. You might say that you aren’t comfortable staying overnight together–your partner does so anyway. He or she might get upset–especially if you try to break up with them or say that you are leaving–however, there is no underlying remorse for hurting you. He or she might say that they are sorry if they hurt you (hit you, scream at you, cheat on you…etc.) and promise that it will never happen again, but their apology is more manipulative than sincere. They might speak badly about a previous partner, claiming that their previous partner was crazy, or a bitch, or an asshole.
They were not of a particularly startling color, shape, or size. Sometimes I ask myself if they are even real, or if perhaps I've conjured them up in an effort to... keep taking, avoid repaying my world and you'll soon find yourself under my knife. I have come to realize how many openly perverted people there are; these guys(for the most part) fan me and message me with no idea of who they are talking to. The mental health agency had not had a walk-in of this kind before.

Psychopaths make up about one percent of the general population (as in, not in a mental institution or jail) and most of them aren’t serial killers.
But it will give you a pretty good idea, based upon the research.
